Determination of an input variable of a vehicle actuator using model-based predictive control

摘要

The invention relates to the determination of an input variable of a vehicle actuator by means of model-based predictive control. According to one aspect of the invention, a processor unit is set up to use an interface to access trajectory information (P) and a status data set (17) which shows an environmental status of the vehicle and / or a status of the vehicle and / or a driving status of the vehicle. The processor unit executes a secondary condition algorithm (14) for calculating a secondary condition (18) and an MPC algorithm (15) for model-based predictive control. By executing the secondary item algorithm (14), a secondary condition (18) for the MPC algorithm (15) is determined as a function of the trajectory information (P) and as a function of the status data record (17). By executing the MPC algorithm (15), an input variable (19) for an actuator of the vehicle is determined as a function of the secondary condition (18). This takes place in particular in such a way that the vehicle follows the predefined trajectory with a predefined certainty in a future predicted trajectory.
